BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 587,446, dated August3, 1897.

Application filed August 26, 1896. Serial No. 604,046. (Model.) l

To all whom, t may concern:

Be it known that I, WILLIAM FITZHUG LEE, a citizen of the United States,residing at Jackson, in the county of Butts and State of Georgia, haveinvented certain new and useful Improvements in Ball-Bearing HubsforBuggies orotherVehicles; andldohereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to certain new and useful improvements inball-bearing hubs for buggies and other wheeled vehicles; and it has forits object, among others, to provide a simple and cheap construction ofball-bearing hub in which larger balls than heretofore used areemployed, thus reducing the liability to crush, and by reason of theballs being larger fewer of them are necessary and the number of pointsof contact are lessened.

-The wheel can be easily unscrewed from the spindle, and the threadingof the cases and check-nuts is so arranged and disposed with relation tothe other parts that the bearing cannot run tight and bind.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention in this instance resides in the peculiar combinations andthe construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, and thenparticularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure l is a substantially central longit'udinal section through ythe hub with the spindle in position. Fig. 2is a view of the buggyhub boxing removed. Fig. 3 is a View of the sleevedetached. Fig. 4 is a cross-section near one end.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thebuggy-spindle, of usual length and of like diameter from inside shoulderto the outside tap end. This spindle from the tap end to within aashortdistance of the shoulder is screw-threaded, as seen at a, the threadsrunning about fifteen 0r twenty to the inch. .Where the threads cease,there is a small shoulder l) for the sleeve, hereinafter described, toab ut tightly against to form a tight joint.

B is the buggy-hub boxing. It is preferably of good steel tubing ordrop-forged and bored out and is about eight inches in length, more orless. The inside of this boxing for about three-quarters of an inch,more or less, is threaded, with the threads running from about fifteento twenty an inch. This threading is to accommodate the ball-cases andthe ball-case check-nuts soon to be explained.

O is the sleeve screwed on the threaded buggy-spindle. The sleeve isthreaded on the inner face the entire length, as seen at o, the threads'runningv the same as those of the spindle and hub-boxing. Thissleeve'screws onto the threads ofthe spindle, as shown, and jointstightly7 against the shoulder b on the spindle.

D is the nut on the outer end of the spindle, bearing firmly against theouter end of the sleeve and preventing` said sleeve from moving eitherforward or backward. This sleeve is shaped near each end to form acone-bearing F.

E are the two ball-cones, one provided with right-hand and the otherwith left-hand threads. f

Gr are check-nuts for holding the cones in position. One is providedwith right-hand threads andthe other with left-hand threads.

vvThe sleeve is provided with a keyhole I, and the buggy-box orbuggy-box bearing is provided with a coincident keyhole J, adapted toreceive the key.

The parts thus constructed are assembled as follows: 'The hub-boxing ispressed into the buggy-hub (not shown) of suitable size. The left-handball-case, which is a right-hand thread, is then screwed into the insidehub end of the hub-boxing sufficiently far to admit of the left-handcheck-nut being screwed in flush with the boxing and up against theball-case. Then insert the forenger from this end, the wheel lying hat.Then drop the TOO balls through the outside end into the abovementionedcase (the finger prevents them from falling out) and then insert thesleeve. The keyhole of this sleeve is coincident with the keyhole of thehub-boxing and that of the hub itself. Then the balls are placed uponthe outside end of the sleeve. The ball-case which has' left-handthreads is now screwed into the outer end of the boxing and down uponthe balls. This is the adj listing-case, and should be screwed tightenough to prevent rattling, but not tight enough to bind on the ballsand retard their freedom of movement. The check-n uts are now screwedinto place on the case. The key made for the purpose is next fitted intothe keyhole in the hub and passed through the keyhole in the boxing andlodges in the keyhole in the sleeve. This key holds the sleevestationary while the same is being screwed onto the spindle by turningthe hub round and round as in going forward. The turning of the hub iscontinued until the sleeve screws up and lits tightly against theshoulder b on the spindle. The spindle-nut is no7 screwed up tightagainst the outside of the sleeve end and the bearing is complete. Itmay be easily removed by removing the end nut on the outside end of thespindle and inserting the key into the hub through the keyholes andallowing it to rest in the keyhole of the sleeve and turning the wheelbackward. After the wheel has been removed from the spindle the positionof the balls remains unchanged.

The size of balls employed is one-half inch, in which case but twelveare necessary at each end, but of course the size and number may bevaried.

Modifications in detail may be resorted to Without departing from thespirit of the invention or sacrificing any of its advantages.

That is claimed as new isl. The combination With the hub-boxing havinginterior threads, of the sleeve having threads its entire length uponits interior, the right and left threaded ball-cases, and. the right andleft threaded cheek-nuts, all substantially as and for the purposespecified.

2. The combination with the threaded spindie, and the hub boxing havinginterior threads, the sleeve` provided with interior threads andcone-shaped ends, the ball-cases and the check-nuts, all substantiallyas shown and described.

3. The combination with the spindle having threads and a shoulder at theend of the threads, of the hub-boxing having screwthreads, the sleevethreaded its entire length, the nut on the end of the spindle, theballcases right and left threaded, and the right and left threaded nuts,all substantially as and for the purpose specified.

4. The combination of the spindle having screw-threads and a shoulder atthe end of said threads, the hub-boxing having interior threads and akeyhole, the sleeve having interior threads and cone-shaped ends and akeyhole, the nut on the end of the spindle, the right and leftball-cases and the right and left check-nu ts, all substantially asherein shown and described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
